How can I get the checkbox value without submitting it?

[elpuchy]

I have a checkbox like so..\[code\]<form action='index.php' method='post'> <input type='checkbox' name='checkme' value='http://stackoverflow.com/questions/14471646/Yes' /> Include Inactive Keys </form>\[/code\]I also have a submit button on the very bottom of the web-page. But when I hit the submit button, I want it to also grab the value of the checkbox (whether it was clicked or not). How can I grab the value?
